Steps 8' and 9,.are rigidly seen-red oonstrtlcted ofienysuita/ble-metal, and-Which is provided withpins 1 1, each equipped with latter of which the striking projection on said rod extends. The channel 13, may be provided at its ends Withrollers 'A, to bear against the inner sides of said end 19 plates, or may itself bear against saidend plates, and is hence held from longitudinal movement thereby, but is free to be actuated transversely the bottom of the door or window by the actuation of the rod 6. As shown, he web of the channel is formed-or rolled to afford a recess therein to receive a strip 18, of felt, rubber or any suitable material to seal'the joint. I i The constructions illlustrated in Figs. 7 20 and 8,'are quite similar;the channel 3, such as before described, is likewise embedded in a suitable groove in the bottom of the door,

but thesprings are differentially disposed.-

In this construction, a tubular extension 19,

is connected with the casing and extends upwardly into a suitable recess therefor in the door, and mounted in each is'a coil spring 20. The thrust rod 21, corresponds withthe rod 6, before described, and is likewise provided with a striking and adjusting cap 7 The sealing bar 22,-is provided with a groove in its bottom to receive a strip 23, of rubber or other suitable material adapted to close onthe surface opposed thereto at the floor or frame; A rod 2 1, is

engaged in the sealing bar and'extends upwardly through the spring. Positively engaged with the upper end of said rod and with'the upper end of the spring through 40 which thesame extends, is a cable 26, the lower. end of which .is connected with one end-ofa coil or spiral spring 27, the other end of'which is connected on thethrust rod 9 '21, remote from the striking head 7. End 5 plates 16 and 17 ,are provided asbefore described, which serve to limitand hold said sealing bar from longitudinal movement, .as before described. b The operation is as follows: Referringfirst to the construction shown in Figs. 1 to 6 inclusive, the closing of the door acts to force the thrust rod 6, inwardly, shifting the cam blocks thereby therewith, and inasmuch as the channel 13, is 'held'from longitudinal movement, said channel bearing the sealing I strip 18, is forced outwardly and into bearing engagement with the adjacent opposed surface of the frame or floor Should the floor, sill or frame not be parallel with-the 0 edge of the door or window to bet-sealed, said sealing strip is nevertheless forced firmly and uniformly thereagainst,-= inasmuch as the cam block adjacent the narrowest portion of the crack or opening will soon come 5to rest, whereupon the spring 11, adjacent that end of the'strip is compressed slightly or sufficiently to equalize thesealing bar or strip perfectly to the threshold or that whichis engagedthereby. When the door is again opened, the spring 28, which is of less strength than the spring '11,and which bears against the sleeve 5-, at its inner end and againsta stop 29, secured on the thrust rod 6, at its outer end, actsto return the thrust rod to normalposit-ion, the stops 8 and"9,"on saidrod, picking up saidfcam blocks and 1 retractingthe weather strip thereby? "The operation of-the strip indicatedaim Figs. and 8,]; is substantially the same. Thespring's 27 permit-independent adjustment of opposite --'endsof thesealing or weather proofing strip to enable thesai'ne' to fit tothe sill or threshold and'when the door :1

is opened, ks'aid springs together with the normal position.

Of course, weather-proofing device be, seated inf'a. groove in the edge of-thedo'or 'or window, for obviously the same may be contained within a suitable casing such'as30', indicated springs 20', act to returni the-thrust rod to 't is not necessarythat the in Fig. 10, and'sc'r'ewedior bolted to th'e face a of the door or-windowwhererequired, as '.i:
